SR780 Network Signal Analyzer
Capture
This example investigates the Capture buffer using FFT measurements. You will use the SR780 to
capture a signal and then analyze it from memory.
1. Press [System]
Display the System menu.
Press
<Preset>
Preset returns the unit to its default settings.
Press [Enter] to confirm Preset.
Preset requires confirmation to prevent accidental
reset. Wait until the self tests are completed.
2. Connect the Source Output to the Channel 1 A
Input.
Setup to analyze the source output.
3. Press [Source]
Select the Source menu.
Press
<Sine>
Choose Sine output.
Press <Frequency 1>
Adjust the output Frequency.
Press [1] [.] [0] [2] [4] select (kHz) with the
knob and press [Enter].
Enter 1.024 kHz for the Frequency. Enter the value
with the numeric entry keys. Select the units with
the knob. Enter the new value with the [Enter] key.
4. Press [Capture]
Select the Capture menu.
Press <Allocate Memory>
The data memory is allocated between Capture,
Waterfall and Arbitrary Waveform storage.
Memory is allocated in blocks. Each block can store
2 kPoints. The total number of blocks available is
displayed in the <Total Available> menu box. This
number is for display only, it cannot be changed
from the menu.
Larger memory options (up to 4000 blocks) are
available.
Press <Waterfall Memory>
To increase Capture memory, you must first
decrease the other allocations so that the sum never
exceeds the total available memory.
Press [0] and [Enter].
Decrease the Waterfall allocation to 0.
Press <Capture Memory>
Select the Capture allocation.
